Abstract: A roll-slide mobile terminal including a first frame; a second frame configured to slide with respect to the first frame in a first direction; a first roller provided in one first-direction end of the second frame; a third frame provided in a rear surface of the second frame; a flexible display unit having one end fixed to the first frame and the other end coupled to the third frame and being bent towards a rear surface when rolled around the first roller; and a drive unit configured to guide a sliding movement of the first frame with respect to the second frame in the first direction to transition the roll-slide mobile terminal from a first state in which the flexible display unit is bent towards the rear surface to a second state in which the flexible display unit is extended in the first direction, and to guide a sliding movement of the first frame with respect to the second frame in a second direction opposite the first direction to transition the roll-slide mobile terminal from the second state to the first state.

Abstract: A rollable mobile terminal comprises: a rolling part bent in a first direction and comprising a flexible display unit and a flexible frame which is bent and located on the rear surface of the flexible display unit; a first body having a cylindrical accommodation part in which one side of the rolling part in the first direction is rolled and stored, and an opening formed in one side thereof through which the rolling part enters and is withdrawn; and a second body to which the other side of the rolling part in the first direction is coupled, wherein the rollable mobile terminal can be changed into a state in which the rolling part is accommodated in the first body, and the first body and the second body are closed, or a state in which the rolling part is withdrawn to the outside and the first body and the second body are separated from each other and open, and, even when the flexible display unit is unrolled, the flexible display unit is stably supported such that a display device is supported and a touch input or the like is possible even when a user holds the rollable mobile terminal with one hand.

Abstract: The present invention relates to a flexible display device, comprising: a first body; a second body configured to be movable relative to the first body; a support plate installed on the rear surface of the second body and configured to be movable relative to the second body; a flexible display unit configured such that areas exposed to the outside are changed while the first body and the second body move relative to each other; and a driving unit generating a driving force such that the second body slides with respect to the first body, wherein as the driving unit causes a movement of the second body through a rotational force by means of a motor, the areas exposed to the outside of the front part and the rear part of the flexible display unit can be changed respectively.
